Working with Multi-level Containers
Specifying Synchronous or Asynchronous Command Execution for a Volume Set of
Mirror Sets
When you create a volume set of mirror sets, you can optionally
specify whether the command prompt returns after the volume set
of mirror sets is created (synchronous command execution) or if the
command prompt returns immediately after executing the
container create mmirror command (asynchronous
command execution). The container creation operation may
require more than a minute to complete.
In the following example, the container create mmirror
command with the /wait switch creates a volume set of mirror sets
synchronously.
HPN0> container create mmirror /wait=TRUE 0 (2,2,0)
Executing: container create mmirror /wait=TRUE 0
(CHANNEL=2,ID=2,LUN=0)
Understanding How to Create a Multi-level Container of Mirror Sets
This section provides an example that describes how to create a
volume set of mirror sets.
Before creating a volume set of mirror sets with the
container create mmirror command, be sure that the multi-
level volume set that is made up of two underlying volume sets has
been created with the container promote command. See
Chapter 9, Modifying Containers, for information on promoting a
container. Use the container list command to display
information about your containers, as in the following example. In
the example, the Type column indicates a multi-level Volume set,
whose container ID is 0, and two underlying Volume sets, whose
container IDs are 63 and 62. These three containers make up a
volume set of volume sets.
